mathematical modelling of control system

The input output relations of various physical components of a system are governed by

• Laplace transform

• differential equations

• both a and b

• none of the above

the ratio of the Laplace transform of the input to the Laplace transform of the output under the assumption that all initial conditions are zero is called transfer function

• true

• false

In the transfer function, the roots of the denominator are

• poles

• zeros

• roots

• ones

In the transfer function, the roots of the numerator are called

• poles

• zeros

• ones

• roots

Applied force is equal to opposing force then

• Newtons first law of motion

• newtons second law of motion

• newtons third law of motion

• none of the above

In ideal mass element, the opposing force is proportional to

• velocity

• acceleration

• displacement

In ideal dashpot element, the opposing force is proportional to

• velocity

• acceleration

• displacement

In ideal spring, Opposing force is proportional to the

• velocity

• acceleration

• displacement

The weight of the mechanical system

• spring

• dashpot

• mass

The elastic deformation of the body is

• Spring

• Mass

• dashpot
